With a top this small you need as close to 100% as you can get. Probly 85. Tops this small are hard to make to heavy.
Material used is also a consideration when designing a top. With a flex material and low fill I would make thicker walls exct....
I would print it with ABS or PETG and use more fill to get the weight up.

I think you'll like it more than you expect when you try it in Cleveland.

Now, this is one is another level  I was curious, so just for fun I printed the 3" top at 10% 5% 0% fill !!!!



It's just two concentric shells. It feels like a beach ball. Not the best top, but I can still freestyle and do most tricks with it. It's fun!

Now that's cool.

Guessing you're already dreaming up tricks to take advantage of your newfound squishiness. How well does this one bounce?

The bouncing is not great and very dependent on the angle that the top has. But this one I can bounce off my head without much fear (there is still that pesky metal tip).

Nice very nice. The trick reminds me of the big Purple Heart top you made.

I experimented a little more by making the Ludo top with a mixed fill: most is 5% fill except the weight ring and the tip section which I printed at 90% fill. This is just one single print: I entered the change in fill in the slicing software.



I think it plays very well while keeping the squeeziness. We'll see what players think in Cleveland.

Thanks Cecil for remembering that top. I need to work on it again.

SO.... Flex tops work and are the future???

Im going to die now!!!!

I whant a relampago with flex material (The same as the sundia diabolos please!!!)

Im becoming crazzy!!!

Yes, they are the future. Yes, we want flexible relampagos.
No, you are not going to die or become crazy.

FLEX SPIN TOPS MY GOD!!!!!

[ta0]

[Note: I split this thread from Jose's 3D thread]

I tried my new flex material, NinjaFlex, and it worked great! 
This material is considerably more flexible than the blue filament: Shore hardness of 85A instead of 95A. I was concerned that the extruder would have trouble with the very pliable filament, but it was not the case.

I printed this top (Jose's Ludo #4) at 15% fill, using no supports, in 6:30 hours:



Great print, well balanced top.
The top is really squeezable and feels great in the hand:





Unfortunately, it's not translucent, so you cannot see the internal structure of the fill.

It is more bouncy than the blue material. Very ball-wise.  I would have no concern of bouncing it off my head. But still to grabby for that trick. I wonder if it could be coated with teflon or something like that.

[jmadrigal]

You could wear a teflon hat
I have been experimenting with this material as well. It took over 15 hours for me to print the 3.2" top. I had two fails before a good top. You have to print this stuff slow.

[Neff]

I’m curious what the takeaway from this experiment will be. Years ago I remember wanting a spin top similar in composition to a Henry’s Diabolo, but I am trying to remember why I wanted one. I think I just wanted the larger size and the durability.

It can’t be a grabby material, that grabs the carpet or your skin in evil bad ways. However that tacky finish is desirable in the snap zone.

It would be nice if a flexible top bounced so that drops could be more easily recovered, but flexible does not necessarily mean bouncy.  Gerardo has a great bounce trick on Instagram, and he is using his normal sized hard plastic trompo. The best bouncing off-string yo-yo’s have a thin but rigid wing. I’m not sure we will get bouncy out of this experiment, instead the flexible is just absorbing the energy and making it bounce less.

Side note – that acorn shape is key for a bouncy spin top.

[ta0]

Great, Jose!
I limited the print speed to 30 mm/s and had a good one on the first try.
What do you think about the top?

It's not supper grabby, but it bounces in the direction of the spin, not vertically. At 15% fill the amount of bouncing would be fine for floor bounce tricks. I suspect at 100% it would bounce even more, but I have to try it.

I'm convinced that "soft-shell" tops are the future.

Sorry for bad pics my phone has problems at the moment...
This is my 3d flexible top printed with filaflex filament, which I think is equal to ninjaflex, 85% infill shiny black, will be available for purchase at Marines and Loon-plage festivals!!!
